Answer:

64.0874 or 20.41pi

Step-by-step explanation:

circumference = diameter x pi

C = D x pi

C  = 20.41pi(lets say pi is 3.14)

C = 64.0874

         Solve for the variable 5=10/t+3.

[tex]\dashrightarrow\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}[/tex]

When solving an equation, we need to make sure that all variables are on the left-hand side, and all numbers are on the right-hand side.

Since we have numbers on both sides, we need to move all numbers to the right:-

[tex]\bold{5=\dfrac{10}{t} +3}[/tex]

[tex]\bigstar[/tex] Subtract 5 on both sides:-

[tex]\bold{0=\dfrac{10}{t} +3-5}[/tex]

[tex]\bigstar[/tex] On simplification,

[tex]\bold{0=\dfrac{10}{t} -2}[/tex]

[tex]\bigstar[/tex] Now, subtract 10/t on both sides:-

[tex]\bold{-\dfrac{10}{t} =-2}[/tex]

[tex]\bigstar[/tex] On simplification,

[tex]\bold{\dfrac{10}{t} =2}[/tex]

[tex]\bigstar[/tex] Multiply by t on both sides:-

[tex]\bold{10=2t}[/tex]

[tex]\bold{2t=10}[/tex]

[tex]\bigstar[/tex] Divide by 2 on both sides:-

[tex]\bold{t=5}[/tex]

Answer:

2048 markers

Step-by-step explanation:

One box has 16 markers and the teacher buys 128 boxes, then total would be

128 boxes x (16 markers / 1 box) = 2048 markers

Length of the rectangle is 8 units

Step-by-step explanation:

Area of the rectangle = 48 units

Length = x + 2

⇒ Area = Length × Breadth

48 = x (x + 2)

48 = x² + 2x

x² + 2x - 48 = 0

x² + 8x - 6x + 48 = 0 (Product Sum rule to factorise)

x(x + 8) - 6(x + 8) = 0

(x - 6)(x + 8) = 0

⇒ x = 6, -8 (negative value is neglected)

∴ x = 6

x + 2 = 8

Answer:

To have one significant figure means to have one number with a significant value. Since all of the answers are greater than one, the final answer with the correct sig figs involves using the two leftmost numbers. If the second leftmost number is greater than 5, round the leftmost number up one unit. If the number is less than 5, leave the leftmost number alone. Finally, change all of the values besides the leftmost to zero. There should be no decimal place because having it would mean the zeros to the left of the decimal place are significant.

Length - 27 cm

Width  - 9 cm

Here we go (hope this helps),

The area of the rectangle is 243. To get area, you do length x width. Your equation will look like this

3x (x) = 243

Simplify this using PEMDAS

3x^2 = 243

Next, you divide both sides by 3 to undo the times 3

x^2 = 81

Then, you take the square root of both sides to undo the squared symbol

x=9

Using this, you know the width is 9. Since the length is 3x the width, you know that 3 x 9 is 27 and you can clearly see that the dimensions are 9 and 27!

Surface Ratio is the "Similarity Ratio" to the power of 2

Volume Ratio is the "Similarity Ratio" to the power of 3

It's logical and deductable by paying attention to the correlation between the "Side"s(or "Diameter"s) and the "Surface" and the "Volume"s in simple shapes like Circles and square.

By paying attention to the formula of the "Surface Area" and the "Volume" or the m /m^2 /m^3 ( the units of measurement) we can easily notice the relation.

An equation is formed of two equal expressions. Felipe is paying $6 more each month.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The equation that represents Felipe's payment per month is given as y=-30+290, therefore, the amount that Felipe pays every month is the gradient of the line slope of the equation y=-30+290 which is 30.

Similarly, the graph showing Samantha's payment, the slope will be,

m = (y₂-y₁)/(x₂-x₁) = (240-0)/(0-10) = -24

Thus, we can conclude that Felipe is paying $6(30-24)more each month, because the amount paid by Felipe is 30, while the amount paid by Samantha is 24.

Hence, Felipe is paying $6 more each month.

The transformation that took place is a horizontal stretch by a factor of 2

We are given that Polygon ABCD transformed to create polygon A'B'C'D'. Clearly, the polygon is first a translation of the polygon ABCD 1 unit to the right and then it is horizontally stretched by a scale factor of 2.

Since the length of the polygon was earlier 2 units and then the length of the Polygon A'B'C'D' is 4 units. Hence, the transformation that took place in the Polygon ABCD is a horizontal stretch by a factor of 2
